“American families and businesses have been paying record-high gasoline prices at the pump even as domestic oil production recently hit its highest level in more than two decades,” Wyden said in a letter to EIA Administrator Adam Sieminski.

In preparation for a hearing on gasoline prices later this spring, Wyden asked the agency to provide data concerning domestic oil production, exports and imports, refining capacity, transportation and mid-stream capacity, and consumption.

“This most recent round of gas price increases has come at a time of year when gas prices are typically at their lowest point, but that has not been the case this autumn and winter,” Wyden wrote.
